MODx CMF

Will be renamed after russian community create instruction how to upgrade from old versions.
And MODX-1024 will be fixed of course.

If we're going to rename the languages, I think it should be done based on ISO standards including language and culture, e.g., pt-PT vs pt-BR ... or zh-Hans-CN (simplified chinese in script). See the RFC 4646 for more info:
http://tools.ietf.org/html/draft-ietf-ltru-registry-14

(It basically combines ISO 639-1 codes, region codes, and script styles)

This needs further discussion

Definitely needs as soon as possible. (if we want to resolve this for 1.0.1)

Could we not just update the upgrade script for this case. In setup.sql:

UPDATE `{PREFIX}system_settings` SET
  `setting_value`='russian-utf8'
  WHERE `setting_name`='manager_language' AND `setting_value`='russian-UTF8';


UPDATE `{PREFIX}user_settings` SET
  `setting_value`='russian-utf8'
  WHERE `setting_name`='manager_language' AND `setting_value`='russian-UTF8';

The problem is that some people (I think) use Windows for webserver.
As you know, windows don't recognize different case in the file name.
If user will make upgrade, and copy new files with overwriting, files will be overwritten, but they still will be uppercase.

Now, if we want to make autodetection (MODX-1071) work properly with russian, need to change case. (or add more checks into installer. that's a bad idea)

I like this way:
ru_ru-utf8
en_us-utf8
or en_US-utf8
